That issue has something to do with one of the shaders (skid marks for one, and dirt tracks for another)
If you do some trial and error you can track down which shader is the one that controls the issue at hand.
What I did was replace each shader folder with a stock shader folder and then, when I found the folder that had the shader
which causes the issue, I replaced each shader in sets of 10 and tracked down the problem shader and replaced it with
a stock shader.

Also, If I'm not mistaken the "VisualIV 1.7.5" is the one that causes the issue.

I could install VisualIV, and track down which one is the problem if you can't find it.

I downloaded VisualIV 1.7.1 and the problem stays, even i used the back up and the problem stay lol

Like I said in my previous comment, you'll have to do some trial an error with the STOCK (stock, as in the shaders that came with IV) shaders, copy a backup of the original shaders over your current shaders. You'll notice a huge difference in graphics but the skid marks will no longer appear. Now, go folder by folder and replace the stock shaders with the new ones (when you replace a single folder, go in game and check to see if the skid marks are showing up again) once you've found the problem folder, you'll have to hunt down which shader it is that causes the skid mark issue.

Edit: is that a photograph of your screen? lololol
You realize with ENB, when you hit "Printscreen" it saves a .bmp to the IV directory right?
So you don't have to whip out your digital camera every time you wanna take a picture of something.

Edit2: The shader that has the skidmark issue is in the "win32_30_atidx10" shaders folder.
Currently tracking down which file is the skid mark now.

Finally i solved my problem, thanks
Now the thing is i cant install enb series ^^ i press shift+f12 and nothing happens

I don't know what the AA file is for, it might have something to do with when you press "P" ingame though, take a look at the difference when your playing with that turned on, and tell me if you notice a difference.

Well i didnt know about pressing P, i did it and there was a difference with AA but almost nothing
